GASOLINE FILTER.

Application filed December 26, 1924. Serial No. 758,212.

This invention relates to an imptroved gasoline Lfilter which isespecially, but not necessarily, designed to be installed in the supplyline to an automobile engine at a point between the main tank and theprimary vacuum tank.

The principal object of the invention is to generally improve upondevices of this class b-y providing one of comparative simplicity anddurability which can be readily installed in opera-tive position Withoutrequiring extensive alteration.

More specifically, I aim to provide a novel filter for the purposespecified which comprises a casing in Which the Water carried by thegasoline is trapped, there being an improved strainer located in thecasing constructed in a manner to intercept the passage of the water butto permit free passage 20 of gasoline.

Other objects and advantages of the invention will become apparent fromthe following description and drawing.

In the drawing:-

The single ligure represents a central vertical sectional view, partlyin elevation, of a gasoline filter constructed in accordance With thepresent invention.

Referring to the drawing in detail, the reference character 1 designatesa vertically elongated casing having a removable cover 2 at its topconstructed to permit attachment of the gasoline supply pipe 3 thereto.As is understood, the pipe 3 lea-ds from and is connected to the maingasoline tank. At its bottom, the casingl is provided With a screwthreaded opening into Which a drain cock 4L is tapped. If desired, apipe 5 may be connected to this cock to carry the liquid to anappropriate point of deposit. At the center of its bottom the casing isprovided with internal and external bosses 6 and 7 respectively provided.with screw threaded sockets. The coupling on one end of a gasolineconducting pipe 8 is connected to the external boss 7 and this pipe, mayif desired, include a valve 9. The improved strainer 10 is arrangedWithin the casing and the same comprises an imperforate base plate 11having a centrally disposed depending screw threaded nipple 12 which istapped into the socket in the boss 6. A cup shaped Wire strainer 13 isfastened about the periphery of the base plate 11. The Wire strainer inthe present instance is covered by a chamois skin lilter, designated bythe numeral 14. This filter is shaped to conform snugly to the shape ofthe strainer and has its lower edge clamped tightly against the bottomof the Wire strainer by a clamping band 15.

Obviously as the gasoline passes from the pipe 3 into'the casing 1, itis compelled to pass through the strainer 10 consisting of the chamoisskin lter and |`the Woven Wire strainer. rThe chamois skin, as is Wellknown, permits unrestricted passage of the gasoline but sheds Waterwhich is trapped in the bottom of the casing to be drained therefrom bythe petcock it Whenever necessary or desired. Should it be desired toclean the trap or remove the strainer, the cover plate t can be takenoff.

A careful consideration of the foregoing description in connection withthe drawing will undoubtedly sufce to enable persons skilled in the artto which the invention relates to obtain a clear understanding of thesame. For this reason a more lengthy description is thought unnecessary.

lVhile I have shown Aand described the preferred embodiment of theinvention it is to be understood that minor changes coming Within thefield of invention claimed may be resorted to if desired.

Having thus described the invention, what I claim is A gasoline filtercomprising a casing which is open at its top, a removable cover platefor said casing, said casing being provided at 'the center of its bottomwith an internal boss formed With a screw threaded socket and a fluidpassage leading from said socket, a strainer Within said casing, saidstrainer comprising a plate provided with a screw threaded nipple tappedinto said socket, a cap shaped screen having its bottom fitted aroundthe periphery of said plate, a chamois skin covering for said screenfitting snugly over the same, and a clamping band for said screen andchamois skin binding the t-Wo against the periphery of said plate, and adrain valve for said casing.

In testimony whereof I affix my signature.
